1. Planting environment
Galla chinensis has the characteristics of being fond of temperature, humidity, drought, cold, barren, waterlogging and water. It doesn't need much soil. Generally, the soil that can grow crops can be used to grow gallnuts. Secondly, there must be horned beam aphid, abdominal bird aphid, summer host plant Rhus chinensis, red bran poplar and winter host moss, that is to say, the planting site must meet the growth of these aphids and parasitic plants, and only when gallnut is planted can the basic conditions for successful planting be achieved.
2. Planting technology
When planting gallnut, we can use the original methods of turning over the forest to replenish trees and artificial afforestation, but the cost of artificial afforestation is too high and the demand for saplings is great, so we'd better use the original method of turning over the forest to replenish trees or afforestation with seed seedlings. Row spacing and plant spacing are generally about 1.5 meters, and up to 22 plants can be planted per mu. Secondly, the species of moss needed by gallnut aphids are selected, and then the moss is cultivated in April and May every year, and the moss generally grows in about three months. Finally, shovel out moss slices 5 cm long and 5 cm wide. Of course, in the process of planting, autumn aphids should still be stocked. We can collect autumn aphids manually, or raise them artificially and stock them in time.
3. Cultivation and management
After the gallnut is planted, it is necessary to observe the growth of young trees and control their potential in time. Generally speaking, in the process of young tree growth, the top of the tree should be removed and the height of the tree should be controlled at about two meters. At the same time, we should prune branches reasonably, mainly diseased branches, dead branches, dense branches and overgrown branches. Secondly, it is necessary to protect the vegetation to avoid damaging the growing environment and affecting the growth of the overwintering host of gallnut. There are some differences between Chinese gallnut planting and other planting, that is, there is no need for intertillage weeding, so the yield and quality of Chinese gallnut will be better. Finally, it is necessary to prevent defoliation, and the effect of controlling defoliation can be achieved by ring cutting on gallnut fruit trees.
4, pest control
Although gallnut needs gall aphids, summer host trees and winter host moss to grow, it does not mean that all pests have no influence on it. So what we have to do is to prepare for the prevention of pests and diseases. The main diseases are anthracnose and black spot, which can be controlled by mancozeb. Of course, carbendazim and thiophanate methyl are also effective. The most important pests are broad-shouldered weevil, longicorn beetle, leaf-eating weevil and so on. Generally, dimethoate can be used to control it.
The above is the gallnut planting technology that School Easy Search wants to share with you today. I hope it can help you. In fact, it seems that planting is not difficult, but the actual operation also requires professional planting techniques, otherwise it will be difficult to plant successfully, which is one of the reasons why gallnut is so rare now.
